Dropbox OAuth2. How to do it?

Hi 3d_Schorsch,

For more info about how you can initiate authorization process, you can take a look here (including how to prepare your authorize URL). There is no such things like token  URL or profile URL. It's your responsibility to organize your users profiles. About the tokens, they are result of the authorization process. You can relay on online token only (short term access, access token), when your code accessing user's Dropbox profile will live in users side browser only, or can use offline token (long term access, refresh token - together with the access one), suitable for server-side dealing with the tasks. On the same page, I just referred to, can be seen most of the access points usable for user's profile access and you may be interested in /2/openid/userinfo especially, and /2/users/get_current_account can be useful too.

Good luck.
